Whatever you do, don't buy and/or try a new brand on your first day out. I have a son who has eczema, and is extremely bothered by any "Banana Boat" brand of sunscreen, even the babies lotion. I put it on him on the way to the beach once, and he screamed so much I had to immediately put him in the bathtub and wash him. This is not how you want your day to start at Disney!! As a previous poster wrote, I also use Oil of Olay with SPF 15 for everyones face. Don't forget the ears!!
